<p class="bodytext">To alleviate security concerns, you may want to restrict administrative access to your control panel from specific IP addresses.</p>
<p class="procedureheading">To allow administrative access to control panel only from specific IP addresses or networks:</p>
<ol class="procedurelistnumber"><li class="procedurelistnumber">Go to <strong class="specialbold">Server</strong> &gt; <strong class="specialbold">Access</strong>.</li><li class="procedurelistnumber">Click <strong class="specialbold">Add New Network </strong>and specify the required IP addresses. Click <strong class="specialbold">OK</strong>.<p class="listcontinue">To specify subnets, you can use wildcard symbols (*) and subnet masks.</p>
</li><li class="procedurelistnumber">Select the <strong class="specialbold">Denied from the networks that are not listed</strong> option, and click <strong class="specialbold">Set</strong>. When prompted to confirm the operation, click <strong class="specialbold">OK</strong>.</li></ol><p class="procedureheading">To prohibit administrative access from specific IP addresses or networks:</p>
<ol class="procedurelistnumber"><li class="procedurelistnumber">Go to <strong class="specialbold">Server</strong> &gt; <strong class="specialbold">Access</strong>.</li><li class="procedurelistnumber">Click <strong class="specialbold">Add New Network</strong> and specify an IP address. Click <strong class="specialbold">OK</strong>.<p class="listcontinue">To specify subnets, you can use wildcard symbols (*) and subnet masks.</p>
</li><li class="procedurelistnumber">Select the <strong class="specialbold">Allowed, excluding the networks in the list</strong> option, and click <strong class="specialbold">Set</strong>. When prompted to confirm the operation, click <strong class="specialbold">OK</strong>.</li></ol><p class="bodytext">By default Plesk allows multiple simultaneous sessions for several users logged into the control panel using the same login and password combination. This can be useful when delegating management functions to other users or in case if you accidentally close your browser without logging out, thus becoming unable to log in again until your session expires. You may want to switch off this capability, if you do not need it.</p>
<p class="procedureheading">To disallow concurrent sessions for your administrative control panel:</p>
<ol class="procedurelistnumber"><li class="procedurelistnumber">Go to <strong class="specialbold">Server</strong> &gt; <strong class="specialbold">Edit</strong>.</li><li class="procedurelistnumber">Clear the <strong class="specialbold">Allow multiple sessions under administrator's login</strong> check box and click <strong class="specialbold">OK</strong>.</li></ol><p class="bodytext"></p>
